Abstract: A simple and computationally efficient model of the hysteretic response of reinforcing bar anchorages under severe cyclic excitations is presented. The model is based on a piecewise linear approximation of the bond stress ...

Abstract: In the assessment of existing reinforced concrete structures, finite-element analysis plays an important role, particularly in regard to the evaluation of critical regions, regions with special detailing, or regions of ...

Abstract: In recent years nonlinear dynamic analysis of three-dimensional structural models is used more and more in the assessment of existing structures in zones of high seismic risk and in the development of appropriate retrofit ...

Abstract: The paper presents a new element for geometrically nonlinear analysis of frame structures. The proposed formulation is flexibility based and uses force interpolation functions for the bending moment variation that depend ...

Abstract: This paper presents an inelastic beam element for the analysis of steel-concrete girders with partial composite action under monotonic and cyclic loads. The element is derived from a two-field mixed formulation with ...

Abstract: A general formulation for torsional-flexural analysis of beams with arbitrary cross section is presented in a general coordinate system. The theory maintains Vlasov's approach in terms of generalized strains and stresses ...

Abstract: Modeling the energy dissipation capacity of shear-yielding members is important in the evaluation of the seismic response of earthquake resistant structural systems. This paper presents the model of a frame element for the ...

Abstract: This paper presents a nonlinear model for pretensioned prestressed concrete girders. The model consists of three main components: a beam-column element that describes the behavior of concrete, a truss element that describes ...
